An infinite number of bodies, each of mass \(2~\text{kg}\) are situated on the \(x\text-\)axis at distances \(1 ~\text m, ~2~\text m, ~4~\text m, ~8~\text m,......\)respectively, from the origin. The resulting gravitational potential due to this system at the origin will be:
1.  \(-\dfrac{8}{3}{G}\) 2. \(-\dfrac{4}{3} {G}\)
3.  \(-4 {G}\) 4. \(-{G}\)
